Answer 2

hi mate,

==> Pisces are the 'group of animals' whose 'heart' does not pump 'oxygenated blood' to different 'parts of the body'

==> In Pisces (fishes), the heart is 2 chambered oral pumps deoxygenated blood to me gills, where oxygenation takes place by diffusion.

==> The oxygenated blood from the gills is supplied to the body parts where oxygen is utilized and CO2 enters H making the blood deoxygenated.

==> This deoxygenated blood returns to the heart. Thus, it has single circulation, i.e., blood passes through the heart only once during one complete cycle.

i hope it helps you.
